NO. 8 NEW AFRICAN UNGULATES — HELLER 9 



general shape of the occipital part of the skull is distinctly Damalis- 

 cus-like. The double infraorbital foramina and the presence of only 

 two lower premolars suggest kinship with Gorgon and Connochcetes, 

 to which genera it obviously has, however, no real affinity. It is 

 apparently a specialized offshoot from the Damaliscus stock. 



The five skulls of Bcatragus in the British Museum agree in the 

 possession of the characters given for that genus. Three of the 

 skulls lack mandibles, but two, recently presented to the museum by 

 Mr. G. Blaine, who secured them on the Tana River, have enabled 

 the writer to determine the dental characters of the genus.
